Winds and wind systems on the Earth. 1  Wind is formed by the flow of air in horizontal directions. In meteorological definitions the coming direction of the wind is called wind direction. 2  1 m/s = 3.60 km/hr = 2.24 mph = 1.94 knot.
The production of proteins involves two major steps: transcription and translation. Together, transcription and translation are known as gene expression. The process of transcription only involves two molecules: DNA and RNA. A DNA strand provides a template for the synthesis of a complementary RNA strand. This process is used to synthesize any type of RNA from a DNA template. Transcription of a gene produces a messenger RNA (mRNA) molecule.
1 Translation is the process by which the nucleotide sequence of mRNA is converveted to the amino acid sequence of a polypeptide.  In bacteria, this process takes place in the cytoplasm.
